Abstract

A multi-unit combined cold extrusion press comprises a base, rod piece joint pressure-welding units and a rod piece connecting sleeve pressure-welding unit, wherein the rod piece joint pressure-welding units and the rod piece connecting sleeve pressure-welding unit are mounted on the base; each rod piece joint pressure-welding unit comprises rod piece pressing arms I and a pressing arm shaft I, and the rod piece pressing arms I form a lever structure by taking the pressing arm shaft I as the fulcrum; the rod piece connecting sleeve pressure-welding unit comprises rod piece pressing arms II and a pressing arm shaft II, and the rod piece pressing arms II form a lever structure by taking the pressing arm shaft II as the fulcrum; and the two or more groups of rod piece joint pressure-welding units are provided, and every two adjacent groups of rod piece joint pressure-welding units are arranged at the intervals required by joints on rod pieces and are fixed in the axial direction of the rod pieces. The multi-unit combined cold extrusion press has the advantages that the connection performance is good, the reliability is high, the operation is convenient and quick, the connection quality is less influenced artificially, energy saving and low consumption are realized, and the multi-unit combined cold extrusion press is green and environment-friendly.

Description

technical field [0001] The invention relates to the field of manufacturing equipment for steel pipe support rods, in particular to a multi-unit combined cold extrusion machine. Background technique [0002] There are many kinds of steel pipe supports in the construction field, which have gradually moved towards regional and industry standardization. The main components are rods, cross bars, diagonal braces and connecting devices. The bar manufacturing process mainly includes the blanking of the bar tube, the manufacture of the connecting device and the connection between the bar tube and the connecting device. At present, the connection between the rod pipe and the connecting device mainly adopts ordinary manual welding and automatic welding. The automatic rod welding machine is a relatively advanced and commonly used equipment in this field, but it has the following obvious defects and deficiencies: ① high energy consumption, for example, 7 welding machines of 11KW are re...
